Validation of service concepts for oil drilling by simulation

We wish to validate various service concepts for oil drilling. A Monte Carlo Simulation is used to generate failure data. We calculate functions for the cost of hiring technicians, purchasing spare parts, fuel, and automobiles for each year of the service period. We also calculate a function for the availability of the wells. We optimize the number of technicians to hire each year in order to maximize the availability while minimizing cost and considering different strategies with respect to spare parts.
